Java Error when calling PLOT command and using graphics.

I am having the following error thrown by MATLAB R2015a, when I try and plot something:

javax.media.opengl.GLException: Profile GL_DEFAULT is not available on X11GraphicsDevice[type .x11, connection :65.0, unitID 0, handle 0x0, owner false, ResourceToolkitLock[obj 0xe0ae46a, isOwner false, <6d19f259, 4275e904>[count 0, qsz 0, owner <NULL>]]], but: []

How can this be fixed. It started randomly as I have not made any changes to the system.

System Info Xubuntu 12.04 64bit MATLAB 2015a Java Version "1.6.0_35" OpenJDK Runtime Environment (IcedTea6 1.13.7) (6b35-1.13.7-1ubuntu0.12.04.2) OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

Hi SG,

From the error it looks like the default OPENGL on your machine may not be compatible with MATLAB. Make sure you have a java.opts file that points to the OPENGL MATLAB installation.

I have the same problem with matlab 2016. No java.opts file exists anywhere in my installation. Furthermore there is no explanation on what a java.opts file should look like, let alone how to set it to point to opengl.

It's poorly documented in matlab I think. Example files are needed.

I have the same problem mo mac os x, my matlab is 2015b. The problem can appear for long matlab running and randomly.
